The new opening of the show is now scheduled to be Bruce Springsteen singing his new song, “We Take Care of Our Own.” It’s a little ironic, but there it is. Following Springsteen, host LL Cool J is set to read a prayer–one rehearsal observer says it includes the words “Our heavenly father.” This will be followed by a video tribute to Whitney Houston. It’s unclear at what point Jennifer Hudison will sing either “I Will Always Love You” or a medley of Houston songs. More to come…"
